cEach column refers to a regression with a different definition for clinics. The first column uses data from the census, which includes additional healthcare establishments but has data for both 2000 and 2010. The second and third columns use data from Urgent Care Locations, LLC (www.urgentcarelocations.com), and include urgent care and retail clinics in column 2 and only retail clinics in column 3, but only include data for 2010.
